Title: Microstrip circulator arrangements
Inventor: BAINS DEVENDAR SINGH
IPC: H01P1/387
Filed: 1984-11-05
Abstract: A microstrip circulator arrangement in which a magnet 9, adjacent a laminar ferrite circulator body 4 on a dielectric substrate 1, is split to provide North and South polarisation of respective areas of the ferrite material, so that clockwise and anticlockwise waves are propagated in respective areas. By rotating the orientation of the magnet, the proportion of input power from input port 6 appearing at an output port 7 of the circulator arrangement can be varied. The ferrite body 4 may have a lossy dielectric body 5 at its centre. The circulator arrangement may act as an attenuator (as shown, with an absorptive load 8) or a 3dB splitter. <IMAGE>
